4. Foldable Time……Rectangles, Rhombi, Squares, Trapezoids and Isosceles Trapezoids Practice: Rectangles, Rhombi & Squares

5. A rectangle is a quadrilateral with 4 right angles. Thm : If a parallelogram is a rectangle, then the diagonals are congruent. Properties of a Rectangle: 1. Opposite sides are ≅ and || 2. Opposite ∠ s are ≅ 3. Consecutive ∠s are supplementary 4. Diagonals are ≅ and bisect each other 5. All four ∠s are right ∠ s

6. Th : If the diagonals of a parallelogram are congruent, then the parallelogram is a rectangle.

8. A rhombus is a quadrilateral with all 4 sides congruent. Thm : The diagonals of a rhombus are perpendicular. Thm: The converse is also true: If the diagonals of a parallelogram are perpendicular, then the parallelogram is a rhombus. If BD ⊥AC, then □ABCD is a rhombus.

9. Thm: Each diagonal of a rhombus bisects a pair of opposite angles. If a quadrilateral is both a rhombus and a rectangle, it is a square. A square is a quadrilateral with four right angles and four congruent sides.
